Facebook will soon forbid users from coordinating private firearm sales using the social network, according to Reuters andThe New York Times. The move, which also extends to Instagram, is a dramatic statement from the company, which has already worked to tighten policies around guns. The new measure applies to public posts; Facebook won’t be scanning through your private messages to uncover gun sales. Also important: this doesn’t apply to posts from licensed gun dealers, which will continue to be permitted on the social network.
